Ever try spreading a little mustard on the outside before frying your grilled cheese?

Add a full cup of sour cream to your scrambled eggs, it sounds insane but they stay super moist and fluffy.

Uh, those are just non-magnetic tweezers.

But isn't some redness just proof the work was thorough?

Oh that's really nice to hear. It's so cool when you see them start to work together like that. What @jadeg99 said about the puppy makes a lot of sense, having a shared responsibility can totally change how they act with each other. Maybe your kids just reached a point where playing together became more fun than arguing over stuff. It's a good feeling to watch them grow up a little bit like that, isn't it?
